A high quality eyepiece filter for reducing the brightness of the moon and improving contrast and surface detail. A moon filter really makes a difference and at such a low cost is a must for every Astronomer.

Due to its ability to produce exceptionally sharp and clear images, this filter is considered one of the most popular astronomy accessories. Significantly reduces light pollution. Sky background is darker.

Color eyepiece filters enhance subtle details on the planets, comets, and the Moon by selectively increasing the contrast between markings of different hues. The eyepiece filter cells are made of anodized aluminum and are double-threaded to permit filter stacking.

The 38A Dark Blue Filter is a popular choice for the study of Jupiter's disc because it strongly rejects red and orange wavelengths in the belts, thus enhancing the boundaries between the reddish belts and the adjacent bright zones.

The original Lumicon 1.25" Ultra High Contrast Filter is unbeatable for revealing nebulosity. This is achieved by passing three nebula emission lines-the two doubly ionized oxygen lines (496 and 501nm) and the H-beta line (486nm)-while blocking light-pollution and Sky Glow.

Due to the design of the transmission curve the filter reduces the sky background and gas nebulas, planetary nebulas as well as open clusters, globular clusters and galaxies are seen better. All major emission lines from deep-sky objects are passed without surpression.The most important part of the eye´s night-sesitive region is passed with maximum transmission.

When we’re in the sunlight, we often wear sunglasses. They help us relax our eyes, protect us from glare, and help us see things more clearly. When amateur astronomers observe the Moon, we use a moon filter.
